CLAMP WITH PIVOTED BENCH MOUNTING MEANS Joseph Olsen, Portland, Oreg.

Application February 11, 1953, Serial No. 336,345

4 Claims. (Cl. 144-304) The present invention relates to new and useful improvements in C-clamps and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which is adapted to be expeditiously secured in position on a work bench or other suitable support to be used in the manner of a portable vise.

Another very important object of the invention is to provide a clamp of the aforementioned character comprising mounting or securing means which, when not in use, may be expeditiously swung to an out of the way position parallel with the bight portion of the frame of the clamp.

Other objects of the invention are to provide a clamp of the character described which will be comparatively simple in construction, strong, durable, highly eflicient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation showing a clamp constructed in accordance with the present invention mounted on a work bench, the latter being shown in section.

Figure 2 is a fragmentary view in end elevation of the device.

Figure 3 is a bottom plan view, showing the mounting means in folded or inoperative position.

Figure 4 is a detail view in transverse section, taken substantially on the line 44 of Figure 1.

Figure 5 is a fragmentary view of a modification.

Figure 6 is a bottom plan view of the modification.

Referring now to the drawing in detail and to Figures 1 to 4, inclusive, thereof in particular, it will be seen that reference character 10 designates a portable clamp comprising a substantially U-shaped frame 11 of suitable metal. The frame 11 may also be of any desired dimensions. At its free end, the leg 12 of the frame 11 is formed to provide a stationary jaw 13. Threadedly mounted in the eye 14 on the free end of the leg 15 of the frame 11 is a screw 16. An adjustable jaw 17 is swivelly mounted on the inner end of the screw 16. The jaw 17 is cooperable with the stationary jaw 13 for clamping the work therebetween, as at 18. An operating handle 19 is provided on the outer end of the screw 16.

Fixed on the end portions of the bight 20 of the frame 11 on opposite sides of the flange 21 thereof are headed rivets 22. Mounting pins 23 are journaled for swinging movement on the rivets 22. As shown to advantage in Figure 4 of the drawing, the pins 23 comprise flattened apertured end portions 24 which are journaled on the rivets 22. Washers 25 are provided on the rivets 22 between the eyes 24 and the flange 21 of the frame 11.

In Figure 1 of the drawing, reference character 26 designates a portion of the top of a work bench or table. The

nited States Patent 0 work bench, table or other support 26 is to have drilled or otherwise formed therein a multiplicity of holes 27 which are spaced to accommodate the pins 23.

It is thought that the use of the device will be readily apparent from a consideration of the foregoing. Briefly, when the device is to function in the usual manner as a clamp, the pins 23 are swung to folded or inoperative position on opposite sides of the flange 21 on the bight portion 20 of the frame 11. This is shown in Figure 3 of the drawing. When the device is to be used as a portable vise the pins 23 are swung outwardly to a position at right angles to the bight portion 20 of the frame 11 and inserted through the desired holes 27 in the support 26 as shown in Figure 1 of the drawing for securing said frame in an upright position thereon. The work, as at 18, may now be readily secured between the jaws 13 and 17 of the device.

In the modification of Figures 5 and 6 of the drawing, pairs of apertured metallic cars 28 are welded or otherwise suitably secured to the end portions of the bight 20 of the frame 11 on the sides of the flange 21 and depend therefrom. Pins 29 are pivotally secured as at 30 for swinging movement between the pairs of the ears 28. The pins 29 terminated in stepped free end portions 31 which lap each other when said legs are in folded or inoperative position as shown in Figure 6 of the drawing. This modified device is used in substantially the same manner as the embodiment shown in Figure 1 of the drawing. However, as will be readily apparent, the depending ears 28 will support the frame 11 on the bench or table 26. Also, the pins 23, when in inoperative position, parallel the free or outer longitudinal edge of the flange 21.

It is believed that the many advantages of a clamp constructed in accordance with the present invention will be readily understood and although preferred embodiments of the device are as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A clamp for mounting on a support having a multiplicity of spaced holes therein, said clamp including a substantially U-shaped frame, coacting jaws on the ends of said frame, and a pair of pins pivotally mounted on the end portions of the bight of the frame and engageable selectively in the holes for adjustably and removably mounting the clamp in position for use on the support, said pins being swingable to inoperative position adjacent to and in parallelism with the bight when the clamp is removed from the support.

2. A clamp comprising a substantially U-shaped frame, coacting jaws on said frame, and a pair of longitudinally spaced pins pivotally mounted on the opposite longitudinal sides of the bight portion of the frame and engageable in a support for mounting said frame thereon.

3. A clamp comprising a substantially U-shaped frame, said frame including a bight portion comprising a longitudinal flange, headed rivets projecting from opposite sides of the flange at longitudinally spaced points, pins journaled for swinging movement on the rivets and engage able in a support for removably mounting the frame thereon, said pins paralleling the flange when in inoperative position, and a pair of coacting jaws on the frame.

4. A clamp comprising a substantially U-shaped frame, said frame including a bight portion comprising a flange, pairs of depending ears fixed to the opposite sides of the flange at the ends of said bight portion, and a pair of pins journaled for swinging movement between the pairs of ears and engageable in a support for removably mounting the frame thereon, said pins terminating in stepped free end portions adapted to extend in overlapping engagement References Cited in the file of this patent UNITED STATES PATENTS Farmer May 3, 1887 4 Sawyer June 20, 1916 Marbach Oct. 28, 1919 Dzurak Dec. 2, 1924 Freeman Jan. 2, 1934 lessen May 1, 1934 Walter Sept. 11, 1934 Strotz Dec. 9, 1947 Larson Aug. 9, 1949
